When it is taught today, metaphysics is often presented as a fragmented view of philosophy that ignores the fundamental issues of its classical precedents. Eschewing these postmodern approaches, W. Norris Clarke finds an integrated vision of reality in the wisdom of Aquinas and here offers a contemporary version of systematic metaphysics in the Thomistic tradition. presents metaphysics as an integrated whole which draws on Aquinas' themes, structure, and insight without attempting to summarize his work. Although its primary inspiration is the philosophy of St. Thomas himself, it also takes into account significant contributions not only of later philosophers but also of those developments in modern science that have philosophical bearing, from the Big Bang to evolution.
